Seoul: South Korea was given prior notice by the United States regarding its decision to permit Ukraine to deploy long-range missiles against Russia, according to the presidential office. The announcement, made on Monday, highlights the evolving geopolitical dynamics as the conflict in Eastern Europe intensifies. According to Yonhap News Agency, U.S. President Joe Biden has reportedly authorized the use of Army Tactical Missile System (ATACMS) weapons by Ukraine to strike targets within Russian territory. This development coincides with the involvement of North Korean troops in combat operations alongside Russian forces, marking a new phase in the ongoing war. A senior official, accompanying South Korean President Yoon Suk Yeol during his visit to Brazil for the Group of 20 summit, informed reporters of the U.S.'s communication with Seoul. Despite this notification, the official emphasized that there have been no discussions between the U.S. and South Korea about providing arms to Ukraine. "As allies, South Korea and the U.S. can exchange necessary weapons if needed," the official stated. "However, I would like to clarify that no decisions have been made, nor have detailed discussions begun, specifically regarding Ukraine." In light of the increasing military cooperation between North Korea and Russia, President Yoon has indicated that South Korea may reconsider its stance on the non-supply of lethal weapons to Ukraine. This potential policy shift signals a significant development in South Korea's foreign policy approach amid the escalating conflict. The situation continues to unfold as global leaders, including President Yoon and President Biden, engage in discussions at international summits, such as their recent bilateral meeting during the Asia-Pacific Economic Cooperation summit in Lima, Peru.
